Ice Dam Removal

What Causes Ice Dams?

An ice dam is a ridge of ice that forms at the edge of a roof and prevents melting snow (water) from draining off the roof. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas. Figure 1 shows a cross section of a home with an ice dam.

How Ice Dams Form

The dam grows as it is fed by the melting snow above it, but it will limit itself to the portions of the roof that are on the average below 32°F. So the water above backs up behind the ice dam and remains a liquid. This water finds cracks and openings in the exterior roof covering and flows into the attic space. From the attic, it could flow into exterior walls or through the ceiling insulation and stain the ceiling finish.

PREVENTION

Nonuniform roof surface temperatures lead to ice dams.After ice removal, proper insulation and ventilation is needed to prevent future ice on your roof. Take advantage of $700 instant rebate if you have less than 6 inches of insulation.
